Fifteen ways to change the world

Kenneth Shinozuka, from New York City, wants to help people with Alzheimer’s Disease, like his grandfather. Kenneth developed a small, wearable sensor to be worn on his grandfather’s foot. When pressure is applied to the sensor, it alerts his family via a mobile app, which allows them to monitor when his grandfather is on the move. By monitoring this behavior, Kenneth hopes to understand the causes of wandering brought on by Alzheimer’s, and to ultimately find a way to mitigate or prevent it.

Samuel Burrow, from the U.K., wants to improve the environment by reducing pollution. Taking inspiration from the chemical used in sunscreen, Samuel created a special coating that reduces waste chemicals in the air when subjected to ambient light. And Cynthia Sin Nga Lam, from Australia, thinks everyone deserves access to clean water and created an eco-friendly and economical device to do just that.

These are just a few examples of the 15 incredible projects we’ve named as the global finalists for 2014 Google Science Fair. This is our fourth time hosting the competition as a way to encourage the next generation of scientists and engineers. From Russia to Australia, India to Canada, this year’s finalists (ages 13-18) are already well on their way to greatness. See all 15 projects on the Google Science Fair website.
